Abstract: A method for solidifying a radioactive iodine-containing waste, in which volatilization of radioactive iodine outward can  be suppressed during solidification, and  a  solidified waste  having  a high level of  confinement  of radioactive iodine  and  a  long term stability can  be  obtained.   The method   comprised   mixing  a  granular  waste   containing radioactive iodine, e.g. a granular iodine adsorbent  having radioactive  iodine adsorbed and collected thereon,  with  a metal  powder,  e.g.  a copper powder,  having  a  corrosion resistance  in an environment of solidified waste  disposal, filling  the  resulting  mixture in  a  metal  capsule,  and subjecting  the  whole to hot isostatic pressing  to  effect solidification.    In   the  resulting   solidified   waste, particles  of the radioactive  iodine-containing  adsorbents are  dispersed  and retained in the sintered matrix  of  the metal powder formed through the isostatic pressing.

Abstract: In marine rescue, this hull penetration system delivers light and breathable air into the air pocket of a capsized vessel, prolonging survival time of persons trapped there and optimising the vessel's buoyancy. The device is mechanically fastened onto the vessel's exposed hull. A drill bit, mounted through the device, is used to bore a hole through the hull into the air pocket without allowing escape of air during or after penetration. Air can be added to or vexed from the air pocket, and special purpose tubes (included with the system) may be inserted into the hull, through an airtight seal in the device. Lights and audio video equipment are mounted in the end of the special purpose tube protruding into the air pocket. Compressed air from portable tanks powers the fastening tool and supplies air for the air pocket, making the system practicable for marine rescue and marine salvage.

Granted: 2004-10-26
Abstract: In a replicated database environment, all nodes (30) monitor the well-being of each other by receipt of node status messages over a network (20). When a node is detected as no longer being alive, the other nodes deduce that such node has failed. When a node failure is detected, a node status record having a nodedown value is written into a nod e log (80) with respect to the failing node. Similarly, when a node comes alive or a new node becomes known to the network, a node status record having a nodeup value is written into the node log. When a local node fails and then is restarted, the local node uses the contents of its node log in order to determine how to initialize the value of a replicated data object. By reading its node log, the local node c an decide whether the data object can be initialized from its disk (32) or not.

Abstract: A package, e.g., carton or box, for a flowable product, e.g., dry cereal. The carton/box has a planar front panel, a planar rear panel, a planar top panel, a planar bottom panel, a pair of planar side panels, and a closure assembly. The upper panel merges with the front panel at a front corner and merges with the rear panel at a rear corner. The upper panel includes two sections, pivotably connected to each other, with one of the sections located contiguous with the front corner and the other contiguous with the rear corner. The upper panel also has a first, e.g., U-shaped, portion arranged to be removed, e.g., torn away, adjacent one of the side panels to form a pouring spout. The closure assembly comprises a first releasably securable connector located adjacent the front corner, and a second releasably securable connector located adjacent the rear corner. The side panels of the package include plural preformed, e.g., weakened, lines located contiguous with the top panel. At least one of the lines in each side panel is severable parallel to the plane of the top panel immediately adjacent the top panel. The other lines in each side panel are foldable. The top panel also has a fold line extending fully thereacross between the two sections making up that panel. The package's spout is arranged to be re-closed by folding the two sections making up the top panel along it's fold line and bringing those portions of the front and rear panels contiguous with the front and rear corners into a confronting relationship with each other, whereupon they become releasably secured to hold the front and rear panels together and to close the spout.
